I’ve been browsing the forums for the last couple days, reading some really good info. I am trying to set up a home karaoke in the basement 15’x35’. So far I am ok with the results but would like some more expert inputs. I’d like my lower feq to be tighter (less boomy) and singing voice a little more natural. My system consists of the following:

Driverack PA+

Fronts: EAW FR153z specs below;
Frequency Response (1 W @ 1m)
3 dB 60 Hz to 18 kHz
-10 dB 48 Hz
Axial Sensitivity (dB SPL, 1 Watt @ 1m)
Full Range 97
Impedance (Ohms)
Full Range 8
Power Handling, AES Standard (Watts)
Full Range 500
Calculated Maximum Output (dB SPL)
Full Range Peak 130.0
Full Range Long Term 124.0
Nominal Coverage Angle, -6 dB Points (degrees)
Conical 100
Recommended High-Pass Frequency
24 dB/Octave 40

Amp: QSC PLX 3602

Sub: JBL PRX618XLF specs below;
System Type: Self powered 18", bass-reflex
Maximum SPL Output: 133 dB peak
Frequency Range (-10 dB): 30 Hz - 105 Hz
Frequency Response (±3 dB): 39 Hz - 93 Hz
Input Connectors: Balanced XLR 1/4 inch combo jack with XLR loop through.
Input Impedance: 20K Ohms (balanced), 10K Ohms (unbalanced)
Signal indicators: Limit : Red LED indicates limiter active condition
Signal: Green LED indicates signal present
Polarity: normal or reverse polarity
Crossover Modes: DSP controlled 48 dB/Oct. filter slope
Crossover Frequency: 90 Hz
Dynamic Control (Input): dbx Type IVâ„¢ limiter circuit

Mixer: Allen& Health ZED 14FX

After I run the auto wizard, I’d like some help with the optimal EQ and crossover settings. I need the basic and then I can fine tune it but I am not really knowledge able about PA system. Any other settings on the driverack, auto EQ, Comp/limiter etc… will be greatly appreciated too, but EQ and Crossover are what I need most.

Also, my sub is sensitive to feedbacks from the mic, don’t know if I should run the AFS again.
Thanks in advance for the help!

    Do you have the HPF applied on the mic's channel?

    I'll check to see if the mic input HPF is set when I go home today.
    I've read the auto EQ and it seems more complicated than I can comprehend so its best not to it then?

    Search post regarding the ato eq function and see if that clears it up some. If not, then don't use it.
